This savory Pizza Bagel Bites Casserole transforms childhood favorite snacks into a hearty family meal that brings everyone to the table. The familiar flavors of pizza bagels expand into a bubbling, cheesy casserole that delivers all the comfort of pizza night with minimal effort.

I created this recipe during a particularly chaotic sports season when my kids were starving after practice but I had zero energy for complicated cooking. Now it's requested at least twice a month, and has become our go to game day tradition.

Ingredients

  • Plain mini bagels: These provide the perfect chewy base that mimics pizza crust while absorbing sauce flavors. Look for fresh ones from the bakery section.
  • Pizza sauce: The flavor foundation of the dish. Choose a high quality sauce with herbs already incorporated for maximum flavor with minimal effort.
  • Mozzarella cheese: Creates that classic pizza pull. Use freshly shredded rather than pre packaged for better melting properties.
  • Parmesan cheese: Adds a nutty depth that elevates the flavor profile. Grate it yourself from a block for best taste.
  • Mini pepperoni slices: These distribute more evenly throughout the casserole than standard size. Look for ones with minimal fillers.
  • Black olives: Provide briny contrast to the rich cheese. Kalamata olives can be substituted for more sophisticated flavor.
  • Bell peppers: Add sweetness and nutrition. Choose vibrantly colored ones for best flavor and visual appeal.
  • Red onion: Offers a mild bite that complements the other toppings. Slice them paper thin for best texture.
  • Italian herbs: Infuse authentic pizza flavor. Fresh herbs can be substituted at triple the quantity if available.

Instructions

Prepare the baking dish:
Coat your 9x13 inch baking dish thoroughly with cooking spray or butter, ensuring you get into the corners. This prevents sticking and makes cleanup easier.
Create the bagel base:
Cut each mini bagel into quarters, then arrange them evenly across the bottom of your prepared dish. Make sure the pieces are roughly the same size for even cooking.
Begin layering:
Pour half the pizza sauce over the bagels, using the back of a spoon to ensure even coverage. The bagel pieces should be coated but not swimming in sauce.
Add first cheese layer:
Sprinkle half the mozzarella and Parmesan cheeses evenly across the surface. The combination of these two cheeses creates the perfect balance of meltability and flavor.
Distribute first round of toppings:
Scatter half of each topping pepperoni, olives, bell peppers, and onions across the cheese layer. This creates pockets of flavor throughout the casserole.
Season with herbs:
Sprinkle half the dried Italian herbs over the toppings. Crushing the herbs slightly between your fingers as you sprinkle releases more flavor.
Repeat layering process:
Create a second identical layer with remaining ingredients sauce, cheeses, toppings, and herbs. This layering technique ensures flavor in every bite.
Cover and bake:
Place foil loosely over the dish, allowing some space for steam to escape. The initial covered bake allows everything to heat through without burning the cheese.
Finish uncovered:
Remove the foil for the final 10 minutes of baking. Watch carefully during this stage for the perfect golden brown cheese top with slightly crispy edges.
Rest before serving:
Allow the casserole to rest for 5 minutes before garnishing with fresh herbs. This resting period helps the layers set and makes serving cleaner.

The mini pepperoni slices are truly the secret weapon in this recipe. I discovered them by accident when shopping for a party, and their perfect size distributes the savory, slightly spicy flavor throughout every bite of the casserole. My daughter, who normally picks pepperoni off her pizza, actually eats them in this dish because they blend so seamlessly with the other ingredients.

Make It Your Own

This casserole welcomes endless variations based on your family's preferences. Try a breakfast version with scrambled eggs and breakfast sausage mixed in, or go Mediterranean with feta, spinach, and sun dried tomatoes. For a spicy kick, add jalapeños and pepper jack cheese, or create a white pizza version using alfredo sauce instead of traditional pizza sauce. The bagel base works perfectly with any flavor combination you can imagine.

Storage and Leftovers

Once cooled completely, store leftovers in an airtight container in the refrigerator for up to 3 days. For best results when reheating, sprinkle a few drops of water over the casserole before covering with a damp paper towel and microwaving. This prevents the bagels from becoming too dry. Individual portions can also be reheated in a toaster oven for a crispier result. The flavors actually develop overnight, making this one of those rare dishes that tastes even better the next day.

Kid Friendly Customizations

Turn this into an interactive family dinner by setting up a topping bar before assembling. Let each family member customize their section of the casserole with preferred toppings. Use cookie cutters to create fun shapes from the bagels before assembling for younger children. For picky eaters, consider creating a half and half casserole with simple cheese on one side and more adventurous toppings on the other. The hands on assembly process makes this a perfect recipe for getting children involved in meal preparation.
